SPIKE-HOLDER FOR SPIKE-DRIVING MACHINEt.

Specification of Letters Patent.

, Patented Nov. a2, 1918.

Application filed January 30, 1917. Serial No. 145,428.

T 0 all whom it may concern:

Be it known that I, ALBERT H. TAYLOR, a citizen of the United States, residing at Easton, in the county of Northampton and State of Pennsylvania, have invented a certain new and useful Improvement in Spike-Holders for Spike-Driving Machines, of which the following is a specification.

This invention relates to pneumatic tools, and especially to a tool of this type in which the article to be acted upon is guided and retained in place by a partof the tool.

The object of the invention is to provide a tool having a guide or holder for the article acted upon which will properly guide and hold the article securely in place during a portion of the time it is being acted upon by the tool. and will be automatically withdrawn from the article during the remainder of the time.

With this and other objects in view, the invention consists in the features of construction and operation set forth in the following specification and claims and illustrated in the accompanying drawings.

In the drawings forming a part of this specification Figure 1 is an elevation of a pneumatic tool provided with my guide or holder.

Fig. 2 is an elevation of the tool, partly in section,

Fig. 3 is a portion of the pneumatic tool provided with my attachment, with the parts in a different position,

Fig. 4 is a section taken on line A-B of Fig. 2, and

Fig. 5 is a parts of this guide or holder.

In the modification selected for illustration, the invention is shown as applied to a tool adapted to drive spikes or other articles into wood or other material. In the drawings is shown a pneumatic tool having a front head 1, provided with an enlargement 2 in which are located slots 3 passing through the enlargement at an oblique angle. Sliding through the slots 3 are fingers 4:, which,

' due to the angularity of the slots 3, are inclined to each other and at their lower ends are adapted to come together and partly surround the spike or other articles to be driven. As shown in Fig. 4, the lower ends of the fingers 4 are preferably shaped to closely fit the spike or other articles to be driven, but this is not necessary, as the tool will act detached view of one of the satisfactorily if the spike is held by the fingers in any suitable manner. In order that the head of the spike may not become misplaced durino; operation, the striking piece 6 isfitted in the front head 1 of the pneu matic tool, so that portion of the trout head 1 beyond the striking piece may provide a socket 5 sufiicient to inclose the head ot' the spike. For convenience in placing a spike in the guide or holder a chain 8 is attached bv one of its ends to the head of one of the fingers and its other end is attached to a handle 7 or any other convenient part or" the pneumatic. tool. By means of this chain the workman can insert a spike in the holder or guide with but one hand 'by raising one ot the fingers i with the chain while the tool is supported with the other. in order that the fingers 4 may not be in the way when the spike is driven nearly into position, the slots 3 are enlarged at their lower portions as shown at 9 in Fig. 2, so that as the lower ends of the fingers 4 take up against the material into which the spike is being driven they can enter these enlargements 9, thus allowing a spike to be driven entirely into place by this tool. Thisds clearly shown in Fig. 3. From the above it is thought that the operation of the guide or holder will be obvious.

It is to be understood that the present showing and description disclose only one specific modification of the present invention and other forms and modifications are included within the spirit and scope thereof, as'expressed in the appended claims.

What I claim is:

1. In combination, a pneumatic tool adapted to drive spikes or similar articles and a device for holding the spike or similar article when the driving starts, said device being arranged to be automatically thrown out of engagement with the spike when said device comes into contact with the material into whichthe spike is driven. 2. In combination,apneumatictool adapted to drive spikes or similar articles and a device for holding said spike or similar article when the driving starts, said device surrounding the spike or similar article and yieldingly engaging the material into which the spike or similar article is driven, said device being thrown out of engagement with said spike or similar article when said spike is partly driven.

3. In combination, a pneumatic tool adapted to drive spikes or similar articles and a device for holding said spikes or similar articles when the driving starts, said device surrounding the spike or similar article and directly engaging the material into which the spike or similar article is driven, said device being arranged to be automatically thrown out of engagement with said spike or similar article when said device comes into contact with the material into which the spike is driven.

4. In combination, a pneumatic tool adapted to drive spikes or simliar articles and a device for holding the spike or similar article when thedriving starts, said device comprising two obliquely extending fingers adapted to surround the spike or similar article, and being arranged to be automatically thrown out of engagement with the spike when said device comes into contact with the material into which the spike is driven.

In combination, a. pneumatic tool adapted to drive. spikes or similar articles and a device for holding the spike or similar articles when the driving starts, said device comprising two obliquely extending fingers slidably mom ited In said pneumatic tool, said fingers adapted to surround the splke or similar article, and being arranged to be.

automatically thrown out of engagement with the spike or other article when said device comes into contact with the material into which the spike is driven.

6. In combination, a pneumatic tool adapted to drivespikes or similar articles, and a device for holdin the spike or similar articlewhen the driving starts mounted upon the front headot' said tool, said device comprising a plurality of obliquely extending fingers slidably engaging slots provided in said front head, said fingers adapted to surround the spike or similar article and being arranged to be automatically thrown out of engagement with the spike or similar article when the spike or similar article is partly driven.

In testimony whereof I have hereunto set my hand.
